7. How to use

CLEAN ALL JOINT SURFACE - Clean all substrate surface and regarding dust oil, frost and any contaminants Wipe polluted parts using solvent and a piece of cloth. Do not use detergent, soap and water.
INSTALL BACK-UP MATERIALS - Backer rod materials such as closed cell polyethylene type can be used as the base of the joint to control sealant depth.
MASK ADJACENT SURFACE WITH MASKING TAPE - Masking tape will ensure a clean, neat appearance and reduce clean up by protecting surrounding areas from excess sealant.
PRIMING - Primer may be needed for optimum adhesion to some substrate surface.
APPLYING SEALANT -Applying sealant deeply into joint. Sealant must be filled into the joint cavity perfectly.
TOOL SEALANT - Tool sealant immediately after sealant application. It helps to provide smooth and flat finish and to ensure that the sealant wets the sides of the joint without any voids.
REMOVE MASKING TAPE - Remove masking tape prior to forming sealant surface skins.
CLEANING - Clean all stuffs around sealant cure area and do not touch when sealant is curing.

8. Limitation

QS119R should not be applied :

To building materials of adhesive hindrance or discoloration that bleed oil, plasticizer or solvent and so on.
In totally confined spaces.
When substrate surface temperatures exceed 50 ℃ and under 5 ℃.
To wet surface (on frost-laden or damp surfaces).
Humid day(over 85% relative humidity day).
For continuous immersion in water or in below-grade applications.
Surface in direct contact with food. Region that paint is required to sealant.
For continuous high pressure and high temperature.
Interior fire prevention section. * Please, check the required properties and class of certification
Joint region that where is expected by physical friction.
Not recommended for use on polycarbonate plastic sheeting, self-cleaning glass, non-staining fluorine coating suitability for use on other type of plastic should be tested prior to application.

10. Handling Precautions

Use at room temperature in the range of 30 to 80 % relative humidity.
Time for complete cure is depend on the thickness of sealant applied.
Adhesion may decline in case of the substrate contaminated. For the best adhesion, clean surfaces thoroughly with solvent before applying the product.
Wear eye protection and protective gloves when handling this product.
Maintain adequate ventilation in the work place at all times.
Keep in place that child’s hand does not touch and never ingest or do not touch in skin
Keep or do work at neighborhood of heat or fire.
Do not use besides service. / Do not inflict shock in receptacle.
Avoid direct ray of light and keep in state that is tightly shut in place that moisture is less.
Do not mixing with other products.
Wash your skins cleanly after work.
As change in quality can be at long term storage, use in validity.
Do not use defected back-up materials. It might induce air bubble.

11. Safety and Storage

Store in original unopened containers in a dry place. Temperature should not exceed 25 ℃ for prolonged periods. (Recommended at 5 ~ 25 ℃)
